With Vector Linear Shaping Circuitry on all channels, the RZ820 handles D/A conversion with no additional noise.

Up to Three Zones of Audio

RZ820 can directly power speakers in a second zone such as in-ceilings or a pair of bookshelf speakers. Or distribute audio to your favorite amp in a second or even third zone using the RZ820 as a pre-amp.

Seamless Integration

The Onkyo RZ Series is engineered for CI. From detachable power cables to optional rack kits, PC setup and support for a wide range of control partners, RZ Series are built for integration.

Zone 2 Video Options

Route 4k video from media players connected to your receiver to a 2nd TV with ease through Zone 2 HDMI or, Sub Out to connect a home theater projector.

With 7.2-channel pre-outs, 12 V trigger, IR input, and optional rack-mount kit, the TX-RZ820 easily integrates other components (such as outboard amps) to create a full wired multi-room setup thanks to Powered Zone 2A/2B and Zone 2/3 Pre-/Line Outputs governed by a Whole Home Audio Mode and supported within Onkyo Controller. RS-232 and IP Control via LAN are ready for home automation systems.

A 4k and HDCP 2.2/HDR-compatible Zone 2 HDMI output allows you to enjoy AV sources connected to the receiver in another room.

DYNAMIC AUDIO AMPLIFICATION. Emotional Impact.

Our premium RZ Series A/V receivers deliver a significant boost to the dynamism, detail, and accuracy of music and movie soundtracks for a listening experience that packs deep emotional impact. The TX-RZ820 features quality components, such as large custom capacitors, to provide high instantaneous current for fast transients and wideband frequency response down to 5 Hz. Discrete non-phase-shift amp circuits clearly focus the audio image and cut distortion even at floor-shaking volumes.

THX®-Certified for Theater Reference Sound

THX Certified Select guarantees the same high-volume sound you experience at a commercial theater in your home. To gain certification, amplifiers must pass the industry’s most severe bench-tests covering every aspect of audio performance. THX Certified Select components are ideally suited to rooms where the screen-to-seat viewing distance is approximately 3 meters (10 ft.), and the room volume is approximately 57 cubic meters (2,000 cubic feet).

To achieve THX® certification, amplifiers must undergo a barrage of the industry’s toughest independent bench testing to satisfy THX® requirements.

4K HDR EYE CANDY

Six rear HDMI® inputs, Main Out, and Zone 2 Out support pass-through of HDR10, HLG (Hybrid Log-Gamma), and Dolby Vision; the BT.2020 4K video standard; 4K/60 Hz video playback; and HDCP 2.2 for premium video content. Front HDMI terminal is ideal for video camera connection, while the Zone 2 output distributes home theater video to a display in a second room.

DYNAMIC AUDIO AMPLIFICATION. IT'S SERIOUS.

Upgraded components, such as the massive transformer and custom capacitors, provide high instantaneous current for lightning-fast transient response and a frequency range that extends down to 5 Hz.

Discrete amp circuits prevent phase shifting for an accurate audio image, cutting distortion even at floor-shaking volumes. It’s a serious build for those serious about sound.

NOISELESS AUDIO PROCESSING

Vector Linear Shaping Circuitry is a mouthful, so we call it VLSC™. This circuitry virtually removes digital pulse noise for a smooth analog signal. RZ820 features VLSC across all channels.

Data is converted between sampling points and these points are joined with analog vectors in real time to produce a smooth output wave form. The result is a virtually noiseless, smooth, analog signal based on the digital source. It brings out even the most subtle of nuances in audio sources.

BREATHTAKING THEATER

Object-based soundtracks allow independently mixed sound to play through any speaker in your system, moving above and around you with breathtaking realism. The TX-RZ820 reproduces 5.2.2-channel Dolby Atmos or DTS:X formats, with AccuReflex correcting the phase of direct and indirect sounds for cohesive audio imaging with Dolby Atmos-enabled speakers.

Stream any music from your smartphone, laptop, or PC to the TX-RZ820 with ease. Control playback with Chromecastenabled apps you know and love from your iPhone, iPad, Android phone or tablet, Mac or Windows® laptop, or Chromebook™.

STREAM ANYTHING WITH DTS PLAY-FI®

DTS Play-Fi® is a wireless protocol that works with any audio app on mobiles and PC. Flick whatever’s playing to the receiver, even different sources to different components at the same time (requires a future firmware update).
